Telkom Sim swap

My Sim card stopped working and called the customer care line, was told I needed to perform a Sim swap at any of their branches. I then informed her that my town had no telkom branch and she informed me that even the spelling of my 1st name on their systems is wrong, so even if I there was a branch nearby I wouldn't b able to perform a Sim swap. So I asked her if my details are correct but for my name, how is it that I should be punished for someone else's error (a telkom agent). She jst politely said the problem and questions I have she cannot answer. I've had the number for more than 10years and I use it for business, and jst like that I have to make peace and say goodbye.
